LED Tube Energy Rebate Guide
DLC QPL certification, utility rebates by state (up to $15/fixture), ASHRAE 90.1 compliance, and Section 179D tax deductions — everything B2B buyers and facility managers need to maximize the financial return on LED tube retrofits.
How Much Can You Save? The Full Rebate Stack
A typical commercial LED tube retrofit qualifies for multiple overlapping incentives. For a 500-fixture office or warehouse, the combined financial benefit often exceeds the product cost:
$3–$15
Utility Rebates
per fixture
DLC QPL required
50–60%
Energy Savings
electricity reduction
vs. T8 fluorescent
Up to $5.65

DLC QPL Application Process: Step by Step
DLC QPL listing is the gateway to most North American utility rebate programs. Here is the complete process — from product testing to rebate application:
LM-79 Photometric Testing
Submit LED tube samples to a NVLAP-accredited laboratory for LM-79 testing. Tests measure total luminous flux (lumens), efficacy (lm/W), color rendering index (CRI), correlated color temperature (CCT), and power factor. Results must meet DLC minimum thresholds: ≥140 lm/W (Standard) or ≥160 lm/W (Premium), CRI ≥80, CCT within ANSI tolerance.
LM-80 Lumen Maintenance Testing
Submit LED chips/modules for LM-80 testing (6,000 hours minimum, 10,000 hours preferred). LM-80 data is used to project L70 lifetime (the point at which lumen output drops to 70% of initial). DLC requires projected L70 ≥ 50,000 hours. TM-21 extrapolation is used to project beyond the tested hours.
DLC QPL Submission
Submit test reports, product specifications, and application fee to the DesignLights Consortium portal (designlights.org). DLC reviews submissions within 4–8 weeks. Upon approval, the product receives a unique QPL listing number and appears in the public QPL database.
Identify Applicable Rebate Programs
Search the DSIRE database (dsireusa.org) or contact your local utility to identify applicable rebate programs. Match your DLC QPL listing number to program requirements. Note whether the program is prescriptive (fixed rebate per fixture) or custom (based on energy savings calculation).
Pre-Installation Documentation
Before installation: photograph existing fluorescent fixtures, record fixture count and location, document existing wattage (typically 32W or 40W per T8 fluorescent tube). Some programs require a pre-installation inspection by a utility representative for large projects.
Submit Rebate Application
After installation: submit rebate application with DLC QPL listing numbers, purchase invoices, pre/post installation photos, and completed application form. Processing time is typically 4–12 weeks. Rebate checks are issued to the building owner or, for midstream programs, to the distributor/contractor.
Utility Rebate Amounts by State / Province
Rebate amounts vary significantly by utility and program. The figures below are representative ranges for DLC QPL listed T8 LED tube retrofits (4ft, 15–18W). Always verify current amounts directly with your utility before project planning, as programs change frequently.
| State/Province | Utility | Rebate Range | Program | Notes |
|---|---|---|---|---|
| California | PG&E / SCE / SDG&E | $5–$15/fixture | California Energy Efficiency Programs | Midstream available; DLC Premium required for max rebate |
| New York | Con Edison / NYSEG | $4–$12/fixture | NY Clean Energy Standard | NYSERDA FlexTech program for large projects |
| Texas | Oncor / CenterPoint | $3–$8/fixture | Oncor Energy Efficiency Program | Midstream available; commercial & industrial focus |
| Illinois | ComEd / Ameren | $4–$10/fixture | Illinois Energy Efficiency Portfolio Standard | Midstream available; DLC QPL required |
| Massachusetts | Eversource / National Grid | $5–$12/fixture | Mass Save | One of the most generous programs; DLC Premium preferred |
| Michigan | DTE Energy / Consumers Energy | $3–$9/fixture | DTE Energy Efficiency Program | Prescriptive rebates for T8 LED retrofit |
| Ohio | AEP Ohio / FirstEnergy | $2–$7/fixture | Ohio Energy Efficiency Programs | Custom rebates available for large projects |
| Washington | Puget Sound Energy | $4–$10/fixture | PSE Energy Efficiency Program | DLC QPL required; networked controls bonus available |
| Colorado | Xcel Energy | $3–$8/fixture | Xcel Energy Efficiency Programs | DLC Standard minimum; Premium for higher tier |
| Georgia | Georgia Power | $2–$6/fixture | Georgia Power Energy Efficiency | Commercial & industrial focus |
| Florida | FPL / Duke Energy Florida | $2–$5/fixture | FPL Business Energy Evaluation | Lower rebates vs. northern states; audit required |
| Canada (Ontario) | Hydro One / Toronto Hydro | CAD $3–$10/fixture | Save on Energy | DLC QPL accepted; DesignLights Consortium recognized |

ASHRAE 90.1-2019 Compliance for LED Tube Retrofits
ASHRAE 90.1-2019 is the primary energy code for commercial buildings in the US, adopted by most states and required for LEED v4.1 certification. Key requirements affecting LED tube specification:
Lighting Power Density (LPD)
- Office: 0.82 W/sq ft maximum
- Warehouse: 0.66 W/sq ft maximum
- Retail: 1.26 W/sq ft maximum
- Healthcare: 0.87 W/sq ft maximum
- T8 LED 15W achieves 40–60% LPD reduction vs. fluorescent
Automatic Controls Required
- Occupancy sensors: most interior spaces
- Daylight harvesting: daylit zones >150 sq ft
- Automatic shutoff: all spaces
- 0-10V or DALI dimming: daylit zones
- Demand response: buildings >25,000 sq ft
Section 179D: Federal Tax Deduction for Commercial Lighting
IRS Section 179D (Energy Efficient Commercial Buildings Deduction), expanded by the Inflation Reduction Act (IRA) of 2022, allows commercial building owners to deduct up to $5.65/sq ft (2026 rate) for qualifying energy-efficient lighting upgrades.
$2.50/sq ft
Base Deduction
25% LPD reduction vs. ASHRAE 90.1-2007
$5.65/sq ft
Maximum Deduction
50% LPD reduction + prevailing wage requirements
5× multiplier
Prevailing Wage Bonus
For projects meeting IRS prevailing wage requirements
For government-owned buildings, the deduction can be allocated to the designer (architect, engineer, or contractor) who certifies the energy savings. Consult a tax professional to confirm eligibility and calculate the deduction for your specific project.

| Item | Calculation | Amount |
|---|---|---|
| Fixtures | 500 × 2 tubes/fixture = 1,000 tubes | 1,000 LED tubes |
| Product Cost (FOB) | 1,000 tubes × $4.50/tube | $4,500 |
| Utility Rebate (avg $8/fixture) | 500 fixtures × $8 | −$4,000 |
| Net Product Cost After Rebate | $4,500 − $4,000 | $500 |
| Annual Energy Savings | 1,000 tubes × (32W−15W) × 4,000h × $0.12/kWh | $8,160/year |
| Section 179D Deduction | 50,000 sq ft × $2.50/sq ft × 21% tax rate | $26,250 (tax value) |
| Simple Payback (excl. 179D) | $500 net cost ÷ $8,160/year savings | < 1 month |
| 5-Year Total Benefit | $8,160 × 5 + $26,250 − $4,500 | $62,550 |
